如何布局Text/Graphics内存

嗨，所有，我有一个问题与T6963C LCD驱动器，我希望有人谁曾与芯片之前可能有答案。对于我正在做的项目，我有一个PIC32启动器套件（PIC32 MX570F512L）+ I/O扩展板连接到一个128x128 GLCD驱动的T6963C。我有PIC接口和写/读没有问题，但是T6963C的行为使我烦恼。我想使用外部字符生成器RAM来存储我自己的更大的字符。我的计划最初是使用四个8x8平方来创建一个16x16字符。但是，现在我发现16x16对于应用程序来说太宽了一点，所以我希望更小，理论上应该通过驱动字体选择（FS）引脚高，使每个字符单元是8x6而不是8x8来实现。我似乎无法找到如何布局Text/Graphics内存，从而在没有图形缺陷的情况下完成这项工作。我最初的（工作没有故障）内存设置如下：0x0000->0x07FF：Text Memory0x0800->0x0FFF：Graphics Memory0x1000->0x10FF：External CG RAMText.= 0x0000->16字节/行图形区域=16字节/行偏移量Reg=0x0002（根据T6963C规范，CG RAM起始地址的前5字节）使用这些设置，我可以显示我的16x16字符，并且画线没有问题。现在，我想使用16x12，因此我增加了每行的字符（字节）数量：0x0000->0x0AAA：Text Memory0x0AAB->0x1554：Graphics MemoryText.=21Bytes/Row（128/6）Graphics=21Bytes/RowOffset Reg=0x0002。当一切都破灭的时候。屏幕重叠，图形绘制出位置。我想我一定是做了一些错误的假设，不正确地设置了内存位置，或者做错了事情。有没有人有T6963C的经验，可以提示我，如果我想做什么是可能的，如果是，我哪里错了？感谢任何输入！

    Hi all,

I've got an issue with a T6963C LCD driver that I'm hoping someone who has worked with the chip before might have an answer to.
For the project I'm working on I've got a PIC32 Starter Kit (PIC32MX570F512L) + I/O Expansion board connected to a 128x128 GLCD driven by a T6963C.  I've got the PIC interfacing and writing/reading with no issues, but the behavior of the T6963C is vexxing me.

I'm looking to use the External Character Generator RAM to store my own, larger characters.  My plan is was originally to use four 8x8 squares to create a single 16x16 character.  However I'm finding now that 16x16 is a bit too wide for the application so I would like to go smaller, which in theory should be doable by driving the Font Select (FS) pin high so each character cell is 8x6 rather than 8x8.  I just can't seem to figure out how to lay out the Text/Graphics memory to accomplish this without graphical bugs.

My original (working with no glitches) memory setup is as follows:
0x0000 -> 0x07FF : Text Memory
0x0800 -> 0x0FFF : Graphics Memory
0x1000 -> 0x10FF : External CG RAM
Text Area = 16 Bytes per Row
Graphics Area = 16 Bytes per Row
Offset Reg = 0x0002 (Top 5 bytes of beginning address of CG RAM according to T6963C spec)

Using these settings I am able to display my 16x16 characters and draw lines with no problems.  Everything is showing up where it should.

Now I want to use 16x12, so I increase the amount of characters (bytes) per row:
0x0000 -> 0x0AAA : Text Memory
0x0AAB -> 0x1554 : Graphics Memory
Text Area = 21 Bytes per Row (128/6)
Graphics = 21 Bytes per Row
Offset Reg = 0x0002

When I put in these settings is when everything breaks.  Screen overlap, graphical drawings out of position.  I figure I must be making some incorrect assumptions, setting my memory locations incorrectly, or otherwise doing something incorrectly.  Does anyone out there have experience with the T6963C that could clue me in to if what I want to do is even possible, and if so, where I'm going wrong?

Thanks in advance for any input!
